SPECIFICATION.

Y To all ywhom t 'may concern:

Be it known that I, JOSEPH W. PRATT, of the town of Edgeield, in thecounty ofDavidson and State of Tennessee, have invented certain new anduseful Improvements in Washing-Machines, of which the following is aspecification:

The object of my invention is to produce a washing-machine and thusavoid the necessity of employing two separate machines for that purpose;and in order to fully describe my invention, that its novelty andusefulness may be observed, I will proceed with the general description,having reference to the accompanying drawing, in which- Figure lrepresents a vertical section through the line Z Z Fig. 2, a verticalsection through the' line X X; Fig. 3, an end view, Fig. 4, a sideelevation.

A is a tub sustained by legs B B. C is a revolving cylinder situated intub A, and is provided with a shaft, D, which transmits a rotary motionto said cylinder from pinion E, attached to the end of said shaft, `intowhich revolves an endless screw or vrm-wheel F, which is attached ,toand revolved by shaft G, which is provided at the opposite end with apinion H, into which works another wormwheel, I, attached to the m/aindriving-shaft J,

which is revolved by crank K and treadle L at the opposite side of thetub. Legs B B also form an upright frame above tub A; into which freelyreciprocates (verticallylthe frame M, to which is connected, byfsprings,N, a vibrating frame, O, provided at the bottom with an elastic roller,P, which is held with great force against the cylinder C by springs, E,located between frames M and O. Frame M receives its reciprocatorymotions from rods QQ, in connection with cranks'S S, which are attachedto shaft J, as shown in Fig. 3:. T is 4a stuffing-box situated in theside of the tub A, through which passes the shaft D. "U U are slotssituated at the top of said tub, directly over the shaft D, into whichthe shaft ends of roller P are 'placed and secured when desired for thepurpose hereafter described. V is a bracket fastened to the side of tubA,

, and acts as a guide for the journal-box at that end of shaft Gr, bywhich means the worm wheel F may be lifted out of gear with the pinionE. W is a bracket-guide employed for a similar purpose at the other partof said shaft. vY is a balance-wheel attached to the shaft J forinsuring the same steady motions.

Operation.

The shaft J being set in motion by the treadle L` and crank K, the frameM is' caused to'reciprocate and the cylinders C to revolve in thedirection of the arrow. The

reciprocation of M causes the roller P to traverse up and down upon therevolving cylinder--the latter of which moves slow, and the former withgreat rapidity. Therefore, wet clothing or fabrics have only to be laidupon the said cylinder to iind their way through a rubbing process and"then fall into the water at the other side of the wheel, (with whichsaid tub is provided,) when they may again be laid upon the cylinder andundergo a similar operation, or as many, as the operator thinks proper,to cleanse the same, after which the wringing process begins. Thisconsists in disconnecting the rods Q Q from the frame M and reversingthe motion of shaft J, and then allowing the wet goods to enter betweenthe roller and cylinder from the bottom and deliver them at the top ofsaid cylinder. Though in practice it will prove more advantageous toreverse the roller P from its present position to the slots at the topof tub A, whereby it may be so fixed as to press heavily upon therevolving cylinder, between which the goods may be passed with certaintyon the part of the operator-that they will be as perfectly dried as bythe use of any wringingmachine now in use.

What I claim as my invention, and desire to secure by Letters Patent ofthe United States, is-A 1. The combination of the reciprocatingrevolving elastic roller P with the revolving cylinder C, as andI forthe purposes above decribed.

2. The combination of the treadle L, crank K, shaft J, worm-wheel I,pinion H, shaft G, worm-wheel F, pinion E, and shaft D, substantially asand for the purpose above set forth. Y

3. The combination 'of the reciprocating s seamen RB, frame O, roller P,rods Q Q, cranks S S slot-s U U, stuffing-box T, brackets V and W andbalance-Wheel Y, as arranged. and. de-

scribed, for the purpose set forth.
